FAQ

Frequently Asked Questions about IGES Viewing

What is an IGES (.iges, .igs) file?

IGES (Initial Graphics Exchange Specification) is an ANSI standard file format for digital exchange of 3D CAD surface models, wireframe curves, and solid geometric information between different computer-aided design systems.

Is my proprietary CAD geometry safe when viewing IGES files online?

Yes, 100%. Our tool runs Open CASCADE Technology compiled into WebAssembly inside your browser. No drawing or CAD entity is ever sent over the internet or saved on cloud servers.

Can I convert IGES files to STL or STEP?

Yes, using our multi-format CAD tool you can load an IGES model and inspect its tessellation directly for rapid manufacturing and 3D printing evaluation.
